Simply posting a graph hardly supports much of anything.

What sets did Panasonic release that had 2.2 gamma in THX right out of the box?

If you search through my posts you will find the results of many calibrations that I have performed.



EDIT: Here is the calibration report for the X1 by D-Nice: http://www.avsforum.com/avs-vb/showt...3#post16014003

For those who don't know how to read the report, I've attached his gamma results going from 0 to 100% stimulus.

No. I'm just saying none of their plasmas have correct gamma for viewing under dim lighting conditions, which is what plasma is intended for.

If you know all about gamma then you would understand why 2.2 is incorrect for a dim surround.



I'm not harping on anything. You asked a question, I answered it.

The exception would be if D-Nice says he can get it up to standard and that anyone else could as well.

Correct, I read on HDJ that their intial Gamma reading was incorrect. It appears that the reading was actually 1.9 (still a little bright I know), but until a proper review is done on the set, I will withhold judgement.

I guess that you still don't understand. When a TV has no gamma control, there is no control over gamma.

The X1 has no gamma control. What I posted it is what it is. Would I like it different gamma for my environment? Maybe but there is nothing I can do about it with this set. Would I want a gamma of 2.4 or greater? Probably not. Understand now?

Good bye,

This is strange and I don't know if he has a bad display because they specifically looked for floating blacks and luminance shifts at VE when they compared the ST30, GTt30 and D8000 and reported they could not see this behavior.

....Unless the THX mode got worse since 2008 (and I imagine it didnt since I would think part of the point is to keep the settings relatively consistent), I very much disagree with this statement. I need to get an additional set to supplement my 2008 model when they first started using THX and I think it's a great mode, and it looking great out of the box (yeah I tried a few tweaks to make it look a little different, perhaps slightly brighter possibly I think), is one of the reasons I gravitated toward that model, as well as getting a panasonic again. I movie watch and game in that mode and it looks pretty damn good to me, and I look forward to supplementiong it with 3 years of TV improvements to boot.



still a little bright??? But all the complaints were that the THX mode was too dim (although I remember hearing this from 2008 as well, people just needed to get used to the comparative difference between that and a vivid mode I felt).
